Some possible rice varieties to be tried out

I have been looking for rice varieties which is suitable in my tilled field and also varieties for my tilled field. My major requirement is that it should survive on rain and also should compete with weeds so that weeding is minimum. Here are some possible candidates which I got from research from WhatsappGroups and talking to friends.

Mapillai Samba - This is of 150 days duration and reaches 4-5 feet height and tasty rice. Ideal for 2nd rice crop, it flowers in November and ready for harvest in January.

Kattuyanam - 6 months duration, 5-6 feet height, again people says, this is cultivated in aadi month of tamil (July) when there is flood like situation in paddy field and harvested in January. I did this one time, and it was started in June and it didn't do well

Chettadi - 6 months duration and good for 2nd rice crop also called as Mundakan crop

Chitteni - 150 days duration and good for 2nd rice crop 

Chambavu - 135-140 days,150-180cm height (one person said 150cm and another 180cm), good taste, good tillering. One person called Prabhavathy confirmed that she had tried Chambavu for 1st crop,May 15th seeds were sown and transplanted in June and harvested by September last.

Yet another person Sasidhararan Master had tried this in 1st crop, he started in June mid and harvested in October, 120-130 days. It was tall, a person standing in the paddy field won't be visible, tasty rice.

Talked to another person called Santhosh in Palakkad who has been doing Matta Chambavu for many years. According to him, duration is 120 days and height will be minimum 4 feet, not much tillering..it may fall, tasty rice. Starting in June may be difficult for 'podi vitha' since it may rain soon heavily and field may be submerged in water, transplanting may be better.

Kayama - 150 days duration, 4 feet height,tasty rice, competes with weeds well. 

Attappadi Upland Rice - According to Durai Swamy of Attapadi, this is sown in Karkkidakam (July-August) and harvested in Vrischikam (November-December). If it is sown early it may reach more height. I tried this once in June and it reached good height, more than 4 feet, but grains didn't form, lots of rice bugs were there, may be because of this or timings was not proper.

Planning to try Kayama this time, Vinod from Nallabhoomi has promised to send the seeds.
