If we look at the picture above sure as a farmer of course we will be amazed by the figure of rice with super long panicles and the number of ears above the average. We certainly slipped the number of crops above 12 tons of per hectare GKP. A fantastic amount, if it is used then per hectare we will bring home no less than Rp. 44 million if the price of grain per quintet Rp. 370.000.

Yes, the figure above is a hybrid rice variety. As a farmer, we certainly know and have planted it in the rice fields. Although not as famous as "half brother" varieties of rice VUB such as Ciherang, Mekongga, Cibogo, Rice Hybrid offers more high yield potential. But alas, our farmers are reluctant to plant it and choose to "cultivate" it into rice if it gets help from the government. Fear of hybrid rice is certainly not completely wrong considering many failed stories of its success. Well through this blog the author tried to peel the hybrid rice.

WHAT IS HYBRID RICE?

Hybrids definitively mean the first derivative (F1) between crosses 2 different varieties. Hybrid varieties can produce higher than the inbred varieties because of heterosis influence which is the tendency of F1 superior to both of its elders. These tendencies appear in all crops, and hybrid rice is expected to appear on potential results.

Following the success of hybrid corn, in early 1970 the worshipers began to apply this method to rice to increase the potential for results. Unlike corn which is a separate male and female flower, the rice hybrid assembly process is more complicated. The rice plants have the perfect flower (male and female organs are located in the same flower). Because it is a female elder rice-forming hybrid that should have a male barren property.

Hybrid Rice Characteristic

Vigor hybrid or heterosis which is the foundation of hybrid result excellence plays a role in the early growth phase. The results showed that the advantages of hybrid varieties result in inbred due to higher biomass production. This is due to the difference in the efficiency of the spare translocation "food" from the stem and the Mideah to the grain in the maturation phase.

Requirements To Grow Hybrid Rice

Because it has a different physiological character with Inbrida Rice then the rice hybrid requires growing suitability. This is very important to be observed before we plant it because rice is more demanding conditions that correspond to the character of Inbrida rice, also land conditions, weather, a heterogeneous pest disease in Indonesia.

Well, from a bit of exposure above the authors expect farmers can measure the suitability of its territory, the selection of planting time, the way of cultivation, etc. So that it will be more optimal to crop yields and the impression of hybrid rice is always detrimental to avoid.

Rice hybrid has the main advantage of its productivity. With a higher production rate is expected to use hybrid rice can be more optimized to the farmers, so that future, can contribute to the increase of rice production of the national.

Different Non-hybrid Rice Seed Characters VS Hybrids

Varieties Of Non-Hybrid
  • The seed is derived from ordinary or traditional crosses. For next-generation seeds, farmers can select themselves from the previous production, usually by choosing the most excellent grain from the most sturdy plants and dense panicles.
  • Average production 5 to 7 tons per ha
  • Examples are the varieties of Ciherang, Cisadane, IR-64, Memberamo, Ciherang, and Sintanur.
  • Varieties Inpari 1 to Inpari 13, Inpago, Inpara, Arize, Intani 1, Intani 2, PP1, H1, and Bernas Prima.
  • Developed long since the beginning of Bimas in the 1960s.
  • Farmers are not very dependent on private seed producers. Seeds can be from farmers ' results from the previous season, with the ability of results that do not decline much.
  • More seed use, but less fertilizer.
  • More robust to pest and environmental attacks (e.g., flooded or drought). Each variety has its advantages.

Hybrid Varieties
  • The technique is more complicated. The first generation individual (F1) is derived from a combination of crosses by involving the cytoplasmic, a Pelestari strain, and a fertility-restoring strain. Production of seed through two stages, namely the production of the old strain, then the production of hybrid seed.
  • The potential yield is higher than the superior varieties Inbrida. Above 9 tons per ha.
  • Varieties Inpari 1 to Inpari 13, Inpago, Inpara, Arize, Intani 1, Intani 2, PP1, H1, and Bernas Prima.
  • Many in the late 2000s. The year 2009 For example there is 500 thousand ha of hybrid rice planting in 20 provinces in Indonesia.
  • Farmers depend on the seed producers of each season. This is why some parties refuse the use of hybrid rice seeds in Indonesia. Seed multiplication can only be done by those who are experts (eg researchers).
  • Instead, seeds are fewer but need more fertilizer. Fertilizer needs more because the adaptation of the environment is low, and maintenance should also be more cautious. More spoiled.
  • The weakness is easily attacked by bacterial leaf blight (crackle), blight, blast, Planthopper, SUNDEP, Beluk, and Caterpillar.
That is an article about Hybrid Rice Varieties vs. Nonhybrid. Hopefully it will be useful for you.
